GAS-SAVING ATTACHMENT FOR BURNERS.

To all whom it may concern:

Be it known that I, ALBERT AoKRoN, a citizen of the United States, andresiding in the city of Pittsburgh, in the county of Allegheny and Stateof Pennsylvania, have invented or discovered new, useful,"and ImprovedGasSaving Attachments for Burntic purposes in many parts of the country.

Experiments conducted by Government agencies show that by moving the gasflame nearer the utensil, water coil or other object to be heated,satisfactory results can be obtained with a very short flame and a verylow service pressure. 7 I

In the case of many of the gas burning appliances now installed, theraising of the burners is diflicult and expensive, and in some casesimpossible.

The objectwhich I have in view is the provision of inexpensive yeteflicient means whereby the raising of theburners in such applianceswill be rendered unnecessaryv while all of the beneficialresults of suchalteration may be obtained at slight expense.

My improved burner attachment not only elevates the flame so that ashorter flame and a lower service pressure may-be successfully used, butI also obtain complete combustion of the fuel and an improved anduniform application of the heat.

In the accompanying drawing, Figure 1 is a top plan View of a gassavingattachment embodying the principles of'my invention; Fig. 2 is anelevation of the same shown mounted on a ring burner, the attachmentbeing broken away in section to show construction and the burnerbeing'indicated in dotted lines; Fig. 3 is a similar view showing amodified form of. the attachment mounted on a gas. burner having no.axial well or opening, and also showing the attachment provided withatop plate of fire- Specification of Letters Patent.

proof material; and Fig. 4 is a similar view of another modification.

The following is a detailed description of the drawings, reference beingfirst had to Figs. 1 and 2.

A represents my improved gas-saving attachment which is preferably madeof metal and may be either pressed or cast in shape; preferably cast.The attachment is mounted as shown on the ordinary gas burner of aheating appliance, such as a range or water heater. Thus I haveindicated in dotted lines at B a gas burner of the ring type having anaxial well or depression.

The attachment is provided with a perimetral, downwardly and outwardlyinclined apron 1 whose outer edge may reston the burner to support thecap in place. The attachment is also provided with a downwardlyextending axial throat 2 which'is intended to be inserted down into thecentral well of'the burner B to prevent the attachment from beingaccidentally knocked outof position. tion surrounding the upper end ofthe throat 2, and 4: is an annular raised portion inter-V posed betweenportions 1 and 3. The raised portion' l is provided with arcuate slots 5for the upward flow of the gas flames.

At 6 Ishow in dotted lines. ports in the upper wall of the throat 2which may be provided for the admission of air to be mixed with theburning gas ascending from the burner B.

When the gas is turned on in the burner B, it rises from the usualburner perfora-' tions and ascends through the arcuate slots 5, formingthe very desirable ring'flame un- If the ports 6 are provided der theutensil.

8 is an annular horizontal porand there is available a good pressure ofgas, the gas flames may pass through said ports 6 'into'the throat 2 andburn at the center of the attachment, thus heating directly the centralbottom of the utensil.

In Fig. 3 I show the. throat-2 shortened to permit-the attachment beingmounted on a star shaped burner C or a burner unprovided with a centralwell'or marked de pression.

Ialso show in Fig. 3 the use of a plate or disk D, of asbestoscomposition, stove clay or other fire-proof material, which fits in thespace 3 and closes the upper end of the throat 2. I prefer to providethe li$k utilized in combustion.

D with a differential edge so as to engage the raised portion 4 without,however, blocking the slots 5. The disk D becomes highly heated andgreatly aids in applying a uniform heat to the utensil to which the heatis being applied.

In Fig. 4 I show the throat 2 provided with a circumferential shoulder 7which limits the downward insertion of the throat 2 in the central wellof the burner B.thus holding the apron 1 above the burner B and therebyadmitting air beneath said apron.

The results obtainedby the use of my improved burner attachment havebeen most satisfactory. The flame is broughtclose up under the utensilor water coil sothat the full heating effect of a short flame isobtained, and good results are assured even when the service pressure isvery low or irregular.

All the gas issuing from the burner is The fact that the slots 5 areformed in the highest portion of the attachmentacts to facilitate thepassage of the. gas flames to the point of ignition and prevents theirbeing'pocketed or husbanded withinthe cap instead of being conveyed tothe flame openings. This is pro'vedby the fact that there is no lateralescape of unburned gas so characteristic of improperly designed devicesfor the purposes in question.

The attachment isinexpensive and easy to apply, andis also durable.

What I desire to claim is 1 A fuel saving attachment for gas burnersadapted to be superimposed on the burner and comprising a centraldownwardly extending cylindrical throat, an annular horizontal portionsurrounding the upper end of said throat, an annular raised portion,surrounding said annular horizontal portion, and provided with gasopenings, and a downwardly and outwardly inclined perimetral apronsurrounding said raised portion. w

2. A fuel saving attachment for gas burners adapted to be superimposedon the burner and comprising'a central downwardly eX- tendingcylindrical portion adapted to be inserted into the central well of thegas burner, an annular horizontal portion surrounding the upper end ofsaid cylindrical portion, an annular raised portion surrounding saidannular horizontal portion, and provided with gas openings, and anoutwardly and downwardly inclined perimetral apron surrounding saidraised portion.

3.. A fuel saving attachment for gas burners adapted to be superimposedon the burner and comprising a central downwardly extending cylindricalthroat, an annular horizontal portion surrounding the upper end of saidthroat, an annular raised portion,
